Three Hialeah voters say they had an unusual visitor at their homes last week: a man who called himself Juan, offering to help them fill out their absentee ballots and deliver them to the elections office.

The voters, all supporters of Democratic congressional candidate Raul Martinez, said they gave their ballots to the man after he told them he worked for Martinez. But the Martinez campaign said he doesn't work for them.

Juan "told me not to worry, that they normally collected all the ballots and waited until they had a stack big enough to hand-deliver to the elections department," said voter Jesus Hernandez, 73. "He said, 'Don't worry. This is not going to pass through the mail to get lost.'"

The story gets a lot more convoluted from there and apparently includes what's described as an "amateur sting operation," though there are no details given on that. There's some circumstantial evidence tying this to Lincoln Diaz-Balart's campaign, but it's shaky at best.

The real story here is that if you're voting absentee, don't give your ballot to anyone under any circumstances. Mail it in.
